*[ANS thanks Jeff Davis, KE9V, AMSAT Secretary, for the above information]* ------------------------------ MESAT1 Telemetry and Testing-Update
The MESAT1 Command and Commissioning Teams wish to thank all that have routinely or even occasionally collected telemetry from MESAT1. Thanks to these reports, the teams are able to make informed and timely decisions about what/when/why/how to do next steps in collaborating with the satellite owners to help with their primary mission. Much is being learned about this new satellite–the University of Maine’s first Cubesat–and AMSAT’s linear transponder onboard. All of the lessons learned will help inform future missions that carry the Linear Transponder Module (or LTM) and the Golf series of satellites. Reports about transponder activities are very helpful, as well.
MESAT 1 *[University of Maine]*
Amateurs are encouraged to visit this link to see in detail all of the callsigns that have contributed to telemetry collection thus far. It’s a lot of stations, all around the world: https://www.amsat.org/tlm/leaderboard.php?id=10&db=FOXDB&show=all&am...
Please continue to collect telemetry! We continue to work on taking and downloading earth images from their cameras. In recent days, we are having the satellite send image blocks both in the mornings and evenings. We expect that to continue in the near future. The transmitter could be on for 5 mins, or perhaps even 10 mins, when over the East coast command stations. Every frame helps us to build an image. Testing is intermittent, but it seems to be more regular right now. When the images aren’t being transmitted, MESAT1 is in SAFE mode, sending a couple frames about every 2 minutes. These frames are very important too!
*MESAT1 was in HEALTH mode, transmitting telemetry continuously, and the beacon setting is pretty strong as of 11:43z on 19 Sept 2024. The linear transponder was enabled at 0050utc on 20 Sept. 2024. Watch AMSAT-BB for announcements regarding MESAT1 status.*

The GreenCube satellite, developed by S5LAB, has likely ceased functioning due to radiation damage. After a successful mission that exceeded expectations, the satellite is no longer responding to commands, and its onboard radio is believed to have been compromised by the harsh radiation environment in Medium Earth Orbit (MEO).
Approximately ten days ago, GreenCube experienced a reboot, and telemetry data from the event did not indicate any anomalies. However, the S5LAB team now suspects that the satellite’s radio was damaged, leading to the current communication blackout. MEO is notoriously challenging for satellites due to its high radiation levels, and GreenCube was not the only satellite affected. Several other CubeSats launched alongside it only lasted a few days, making GreenCube’s extended mission duration a remarkable achievement.
Despite ongoing efforts to send commands and reactivate the satellite, the team remains pessimistic about restoring GreenCube’s functionality. The satellite’s survival in the hostile MEO environment is seen as a testament to its robust design, but the likelihood of recovery is slim.
At this time, no successor to GreenCube is planned, primarily due to the infrequency of launch opportunities to MEO. Launches to this orbit are rare, which complicates the prospect of future missions.
In response to the satellite’s success and the interest it generated among radio amateurs, S5LAB has promised to host a webinar in collaboration with AMSAT Italia. The event will provide insights into the GreenCube mission, sharing the challenges and triumphs of the satellite’s journey. This is an opportunity for the amateur radio community to learn more about the satellite’s impact and the technical details behind its impressive mission.
While GreenCube’s operational life may have ended, its contributions to satellite technology and amateur radio will be remembered as a significant milestone.

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/
No changes have been announced for this week.

The crossband repeater continues to be *ACTIVE* (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.
The packet system is currently *MISCONFIGURED* (145.825 MHz up & down). Ham TV is currently *STOWED* (2395.00 MHz down). SSTV is currently *STOWED* (145.800 MHz down).
As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. *POWERING OFF FOR SOYUZ UNDOCKING ON SEP 23*.

+ NASA astronaut Don Pettit, KD5MDT, alongside Soyuz commander Alexey Ovchinin and cosmonaut Ivan Vagner, arrived at the International Space Station Wednesday, September 11 after launching aboard the Roscosmos Soyuz MS-26 spacecraft from the Baikonur Cosmodrome in Kazakhstan. The trio will join NASA astronauts Tracy C. Dyson, Mike Barratt, KD5MIJ, Matthew Dominick, KCØTOR, Jeanette Epps, KF5QNU, Butch Wilmore, and Suni Williams, KD5PLB, as well as Roscosmos cosmonauts Nikolai Chub, Alexander Grebenkin, and Oleg Kononenko, RN3DX.

+ Tracking sleuth Scott Tilley, VE7TIL, has discovered that the orbiter for China’s Chang’e-6 lunar sample return mission is now parked at the second Sun-Earth Lagrange (L2). After delivering the samples to Earth, the orbiter fired its engines to avoid reentering Earth’s atmosphere, setting off on a new trajectory. L2 is located approximately 1.5 million kilometers from Earth, directly on the opposite side of the Earth from the Sun. China’s space authorities have yet to provide an update on the orbiter and its plans. However, the Chang’e-6 orbiter’s voyage fits into a pattern of China using Chang’e spacecraft for extended missions as tests for future endeavors. (ANS thanks Space News for the above information.)
